Multiple police units descended on Ninewells Hospital in Dundee after a prisoner allegedly kicked off inside.
At least four police vehicles were seen arriving at the entrance to the hospital, near the bus stances, just before 10am on Thursday.
Onlookers saw officers and staff from a GeoAmey prisoner transfer van running into the building.
Police left the scene shortly before midday, but a 40-year-old man will be reported over the incident.
A spokesperson for GeoAmey advised the prisoner was on an “escorted visit” to the hospital before officers were called.
One man told The Courier he saw two GeoAmey vans at the scene alongside the police response.
‘Folk were concerned’
He said: “It was some carry on, the police vehicles were scattered across the main entrance to the hospital.
“The prison transfer vans were parked at a separate location but two of the workers were running towards the main concourse.
“Folk were a bit concerned by what was going on.
“I saw at least eight officers coming out of the hospital just before midday.”
A GeoAmey spokesperson said: “During an escorted hospital visit today of a person in custody, their behaviour became aggressive and violent giving our officers cause to call Police Scotland to attend and support.
“We can confirm that the person remained in secure custody at all times and there was no threat to the public.”
A Police Scotland spokesperson added: “Around 9.50am on Thursday, police received a report of a man causing a disturbance at a hospital in Dundee.
“Officers attended and a 40-year-old man has been reported to the procurator fiscal.”
A Scottish Prison Service spokesperson said: “We are aware of an incident at Ninewells Hospital, Dundee, which has been managed by GeoAmey.
“The matter has been reported to Police Scotland.”
A spokesperson for NHS Tayside said staff alerted officers to the incident.
They added: “There was no impact on services.
“As this is a police matter we are unable to provide further comment.”
